Datos San Francisco
Buying city pass on altraz cruises on pier 33, they make you a big discount for the alkali tour that I totally recommend and it's the only place that sells it, inside the prison there's a really good audio tour. With the city pass you save all the cable car, buses and MUNI metro (says x 3 days), but they are relaxed when checking tourists. I recommend tb BIG BUS to take a general tour of the city and get back to what you're interested in. Beautiful, quiet, friendly San Fco town.
